EXCAVATING-SCOOP.

SPECIFICATION forming part of Letters Patent No. I791,390, dated May 30,1905.

Application filed June 10, 1904. Serial No. 212,006. l

To all whom, it may concern:

Be it known that I NICHOLAS Winsen, a citizen of the United States,residing at Redoak, in the county of Montgomery, State of Iowa, haveinvented certain new and useful Improvements in Excavating-Scoops; and Ido hereby declare the following to ,bea full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to excavating-scoops, and has for its object toprovide a scoop for use in connection with a loading chute in which thescoop may be used for excavating as well as for conveying the looseearth to vehicles.

A further object is to provide a scoop having an excavating-blade, whichmay be moved into operative or inoperative position, as desired.

In the drawings forming a portion of this specification, and in whichlike numerals Iof reference indicate similar parts in the several views,Figure 1 is a perspective view of the scoop. Fig. 2 is asideelevation ofthe loadingchute, showing the scoop thereon. Fig. 3 is a side elevationof the scoop in the act of dumping its load. Fig. 4 is a longitudinalsection taken vertically through a portion of the scoop andexcavating-blade.

Referring now to the drawings, there is shown a scoop 5, opened at itsforward end 6 and having an excavating-blade 7, hinged to the forwardedge 8 of the bottom of the scoop through the medium of rings 9 engagedthrough holes 10 in the bottom of the scoop and rear edge 'portion ofthe excavating-blade. The forward edge 7 of the blade is beveledupwardly to forma cutting edge 9, 'and the ends 10 and 11 of the bladeare turned upwardly at right angles beyond the sides of the scoop andhave secured thereto the free ends of a rearwardly-extending yoke 12,having a handle 13 attached thereto. Connected with the angular ends 10and 11 of the blade', by means of a curved bar 14C, is a cable 15, bymeans of which the scoop may be drawn out of the ground, and through themedium of the handle 13 and yoke 12 the cutting edge 9 of the blade 7may be moved downwardly to engage the earth, the latter being cutthereby and passing into the scoop. The handle 13 may also be used toguide the scoop. When it is desired to move the blade 7 out ofengagement with the earth, the handle 13 is moved downwardly tosufficiently elevate the forward edge of the blade and a latch 16 isengaged with a projection 17 to hold the handle in this position, itbeing understood that the latchis attached to the handle. In thisposition the side members of the yoke rest their rearward ends uponmembers 18 and 19, which are attached to the sides of the scoop, asshown.

The scoop just described is employed in connection with a loading-chute20, including an inclined plane 21, supported by uprights.

22, and which has projecting beyond its upper end, at the sides thereof,a pair of arms 23, having notches 24 in their upper edges. The cable 15,by means of which the scoop is drawn over the ground, is passedlongitudinally over the inclined plane 21,so that after the excavatingoperation has been completed and the scoop is lled with earth it will bedrawn onto the inclined plane, up which. it will travel to the arms 23,which are so disposed that they receive upon their upper edges trunnions25, which project from the sides of the scoop, it being understood thatthe cable 15 is connected with a hoisting-engine or other source ofpower 26. When the forward end of the scoop has passed suiiiciently farbeyond the upper end of the plane 21 to engage the trunnions 25 in thenotches 24:, the weight of the forward end of lthe scoop causes it toturn upon the trunnions and its load is deposited into a wagon or car27, placed into position to receive it.

A rope 28 is attached to the lrear of the scoop at one end, to which ahorse may be attached to draw the scoop to the bottom of the chute afterthe operation of dumping.

In practice modifications of the speciiio construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from the spirit of the invention.

What is claimed is- 1. In a loader, the combination with an in- 10oclined plane having arms extending beyond its upper end, saidl armshaving notches in their upper edges, of an excavating-scoop having anopen end and trunnions projecting from its sides arranged for movementlongitudinally of the plane to bring its trunnions into engagement withthe notches, said trunnions being arranged for movement in the notchesto permit of downward movement of the open end of the scoop, acutting-blade hinged to the scoop for movement to bring its cutting edgeabove and below the bottom thereof, and means for holding the blade inthe first-named position.

2. An excavating-scoop comprising a receptacle open at its forward end,a cutting-blade pivoted at the forward end of the receptacle formovement to bring its cutting edge above and below the bottom thereof, arearwardlyextending yoke secured to the blade, a handle attached to theyoke for movement thereof, to move the blade pivotally, a latchconnected with the yoke and arranged for engagement with aprojcctionupon the receptacle to hold the blade with its cutting edge above thebottom of the receptacle, and means for connecting a cable with thescoop.

ln testimony whereof I aix my si gnature in presence of two witnesses.

NICHOLAS VVIESEN.
